# Japan CMBS issuance structure — named-deal evidence guide

## TL;DR

The prior page generalized TMK/GK-TK preference, standard tranching, rating, servicer, post-2008 defaults and a 2020 logistics-led revival without a defined transaction set. Those claims are removed. A CMBS must be described from the named issuer, collateral, loan, vehicle, waterfall, servicing and dated rating / performance documents.

## Wiki route

Use this page with [[structured-finance/tmk-special-purpose-company-mechanics]], [[structured-finance/spv-tk-gk-vehicle-japan-tax]], and [[structured-finance/credit-rating-methodology-jcr-r-and-i]].

## 1. Named transaction

[JCR's public structured-finance rating list](https://jcr.co.jp/en/ratinglist/sf_sf/) is one entry point; the following table states the full evidence required.

| Field | Required public evidence |
|---|---|
| Issuer / vehicle | Offering and legal documents |
| Borrower / sponsor | Loan and transaction disclosure |
| Collateral | Property / mortgage / trust-interest definition |
| Loan terms | Principal, maturity, amortization, covenants and recourse |
| Notes / interests | Class terms and payment priority |
| Rating | Dated class-specific action and criteria version |

## 2. Vehicle boundary

[The Asset Securitization Act](https://laws.e-gov.go.jp/law/410AC0000000105) establishes the TMK-law boundary in the following table, not a CMBS market preference.

| Vehicle claim | Required evidence |
|---|---|
| TMK | Named issuer, notification / plan and offering document |
| GK plus TK | Formation, TK and asset documents |
| Trust beneficial interest | Trust deed and transfer / offer terms |
| Public or listed | Offer filing and exchange record |
| Tax / accounting | Current law plus transaction-specific analysis |

## 3. Cash flow and servicing

[JCR's methodology library](https://www.jcr.co.jp/en/rrinfo/meth_sf/) supports the following analytical checklist.

| Field | Required named-deal evidence |
|---|---|
| Property cash flow | Rent roll, expenses, vacancies and valuation date |
| Debt service | Interest, amortization and balloon terms |
| Waterfall | Fees, interest, principal and loss allocation |
| Reserves / hedges | Funding, uses, counterparties and replacement terms |
| Servicer / special servicer | Appointment, transfer event and powers |
| Refinance / sale | Assumptions and contractual timing |

## 4. Historical analysis

[JSDA's securitization-market survey](https://www.jsda.or.jp/en/statistics/securitization-market/) supports the following method.

| Claim | Required evidence |
|---|---|
| Issuance trend | Defined JSDA category, period and revisions |
| Default | Named loan / note event and date |
| Loss / recovery | Trustee, servicer or rating disclosure |
| Property-type trend | Named transaction set and cutoff |
| “Shutdown” / “revival” | Defined threshold and calculation |

## 5. Deferred claims

Vehicle dominance, standard tranches, agency combination, investor base, default-wave magnitude and current revival remain deferred without a defined public transaction population.
